Hello, and welcome to Show Me Cables. Today we’re going to take a look at the difference between modular plugs.
Modular plugs are used in many different voice, data, and control signals and are available in a variety of styles.
The first plug we have is known as an RJ22.
This is the smallest of the modular plugs and is mostly used on handset cords. It is known as a 4P4C, which means that it has 4 positions and 4 contacts.
The RJ11 is slightly larger than the RJ22 and found on line cords, used for telephone wall plates and control signals. It is known as 6P4C, which means that it has 6 positions and 4 contacts.
The RJ12 is the same size as an RJ11 and is also found on many line cords and is commonly used for telephone and control applications. However, the RJ12 is a 6P6C, meaning that it has 6 positions and 6 contacts.
RJ12 connectors can be used in place of RJ11 applications, but RJ11 may or may not work in place of RJ12, depending on if the additional 2 contacts are needed.
RJ45 connectors are slightly larger than the RJ12s and are used for Ethernet and data applications. They are known as an 8P8C, which means that it has 8 positions and 8 contacts.
If you still have any questions, you can call our customer service department at 888-519-9505.
